Answer:
The Stoics were Ancient Roman philosophers who claimed that the ideal state of mind was tranquility, which can not be achieved by pursuing enjoyable experiences, but by developing a calm indifference towards one's circumstances. This is a concept that opposes what Burkeman calls the modern-day cult of optimism, which forces us to try to find the good in bad situations. Burkeman explains there´s an alternative “negative path” to happiness, through the acceptance of the things that could go wrong.
Step-by-step explanation:
I personally agree with this philosophy, as it´s very similar to the kind of strategy I found to deal with my anxiety. Instead of constantly worrying about what could go wrong, I trained myself to recognize which fears were a real possibility and changed my mindset to accept that not everything is under my control, and that is ok.
